Built from galvanized steel, it measures 6 inches in diameter and ships with a motor included. The crimped edge design creates a true-size fit that seats cleanly inside standard round ductwork without requiring additional hardware. A single set screw locks the motor in place, and the one-blade configuration allows smooth operation with efficient sealing for reliable airflow control across heating and cooling zones. HVAC technicians and sheet metal contractors install this damper as part of zoned air distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light commercial zoning applications where round duct runs require automated airflow control. The round housing is compatible with flexible ducting as well as round sheet metal duct, making it a practical choice for both new construction and retrofit installations. It is typically installed in the supply trunk or branch runs of forced-air systems where zone control is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-inch diameter round housing for direct fit in standard round duct\u003c\/li\u003e\n  \u003cli\u003eGalvanized steel blade construction for durability in conditioned-air environments\u003c\/li\u003e\n  \u003cli\u003eMotor included — no separate actuator purchase required\u003c\/li\u003e\n  \u003cli\u003eCrimped edge design ensures true-size fit and consistent seating\u003c\/li\u003e\n  \u003cli\u003eSingle set screw secures motor without complex fastening\u003c\/li\u003e\n  \u003cli\u003eSingle-blade design delivers smooth operation and efficient airflow shutoff\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 6-inch diameter flexible ducting or round sheet metal duct in forced-air zoning systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler and disconnect power to the system before installing or wiring the damper motor. Secure the damper in the duct run per local mechanical code requirements, and verify low-voltage control wiring connections at the zone controller before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 6 inches diameter\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Round, Motorized, Single Blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInclusions\u003c\/strong\u003e: Motor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DUROZONE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 35039\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DUROZONE","offers":[{"title":"Default Title","offer_id":51284000801074,"sku":"35039","price":183.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277684.jpg?v=1781065622","url":"https:\/\/voomisupply.com\/products\/durozone-35039-round-motorized-duct-damper-6-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
